ADJUSTABLE CONE-FASTENING FOR BALL-BEARING AXLES.

SPECIFICATION forming part of LettersPatent No. 631,445, dated August22, 1899.

Application filed May 21,1898. Serial No. 681,391. (No model.)

To all whorrt it may concern:

Be it known that I, CHARLES S. SMITH, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State 5 ofWisconsin, have invented certain new and useful Improvements inAdjustable Cone- Fastenings for Ball-Bearing Axles, of whichthefollowingisaspecification,referencebeing had to the accompanyingdrawings, forming a part thereof.

The main object of my invention is to provide an adjustablecone-fastening for ballbearing axles that will be secure and reliable inuse and that will bring into service a different bearing-surfacewhenever theoone is adjusted, thus tending to make the cone wear moreevenly and longer.

It consists of certain novel features of construction and combinationsof parts hereinafter particularly described, and pointed out in theclaims.

the center of the axle.

A represents the spindle of a vehicle-axle, which in the presentinstance is shown as of tubular form throughout, although it may be madesolid except at the outer end, which must be tubular or bored out andthreaded axially to receive the expanding-screw of the cone-fastenin g.B designates the inside cone, and C the outside cone, which is threadedupon the outer end of said spindle. spindle has in its outer end one ormore 1ongitudinal saw cuts or slits a, whereby it is made expansible andcontractible.

D is a screw threaded in the bore of the axle and provided with atapering or cone-shaped head 01, which is fitted in acorrespondinglyshaped seat in the outer end of the axle-spindle, asshown in Fig. 1.

The

The cone C and the screw D are provided with means for turning them. Thecone may for this purpose be flattened on opposite sides, as shown at cc in Fig. 2, to receive a wrench, and the screw D may be formed with awrench-head or flattened extension 0? on its outer end, as shown inliig. 1. The outside cone C is adjusted toward the inside cone B to takeup wear by turning it up on the threaded end of the axlespindle. Toeffect this, the screw D is slack ened or turned out sufficiently toallow the slit portion of the spindle to contract and the cone to turnthereon. After the cone is set up and adjusted it is locked in place bytightening the screw D and expanding the threaded end of the spindle insaid cone.

In devices of this class it has been customary heretofore to fit theoutside cone loosely upon the axle, to hold it from turning thereon byapin or key and keyway, and to adjust and secure it in place by aflange-bolt tapped in the axle-spindle and locked in position by asetscrew passing through the center of the same; but this method ofmounting, adjusting, and fastening the cone is objectionable because thecone is not positively held in proper alinement or adjustment relativeto the inside cone, and as it is not turned in its adjustment but onepoint or face is subjected to wear, thus causing it to soon becomeuntrue and to work imperfectly. With my improved fastening, however, theoutside cone is turned every time itis adjusted, thus bringing a newwearingpoint or face into play, tending to distribute the wear, preservethe proper shape,

and prolong its serviceable condition.

The axle-spindle need not necessarily be formed in the outer end of itsbase with a tapering or cone-shaped seat for the head of theexpanding-screw D, which will work without or will with use form foritself a sufficient seat- The minor details may be modified in variousways without materially aifecting the operation of the device ordeparting from the principle of my invention, and therefore I do notwish to be understood as limiting myself to the exact details ofconstruction shown in the drawings and specifically described, except tothe extent that they are expressly included in the claims.

I claim 1. The combination with an axle-spindle having a threaded holein the end which is longitudinally split and externally threaded, of aninternally-threaded cone fitted to engage the external thread on saidspindle, and a screw fitted to engage the threaded hole therein andhaving a plain cone-shaped eX- panding-head, substantially as and forthe purposes set forth.

2. The combination with an axle-spindle having an axial hole terminatingin a plain beveled or tapering seat and longitudinally split throughsaid seat, of a cone threaded upon the split end of said spindle, and ascrew threadedin said hole and having a plain coneshaped expanding-headfitted in said tapering seat, substantially as and for the purposes setforth.
